[R] Power graph for two Proportion

Dear R mailing listers, I am try to find the different power calculation for p1=0.2 and p2=0.4 , with significant level=0.05 (one sided test) I would like to have a graph y -axis as a power and x-axis as a sample size . I run this command for different value of power. and get the n and power

Re: [R] Power graph for two Proportion

Suga, Perhaps something like this ... library(pwr) n <- 50:100 power <- pwr.2p.test(h=ES.h(0.4,0.2), n=n, sig.level=0.05, alternative="greater")$power plot(n, power) Jean On Mon, Jun 16, 2014 at 10:44 AM, Suganthie Jeyaganth wrote: > Dear R mailing listers, > I am try to find the different p
